What We regard as new, and desire to secure by LettersPatent, is

1. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a revoluble receiving-vessel adapted to receive molten material to be treated, an annular tub surrounding the same and adapted to receive the molten material discharged from the mouth of the receiving-vessel, a removable cover for such tub to retain the heat of the molten material therein, a revoluble actuating-shaft rotating the receiving-vessel as it revolves, and means for rotating the actuating-shaft, substantially as described.

2. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a revoluble receiving-vessel adapted to oeive molten material to be treated, an annular tub surrounding the same and adapted to receive the molten material discharged from the mouth of the receiving-vessel, a removable cover for such tub to retain the heat of the molten material therein having a -depressed central portion forming a cover over the neck or mouth of the receiving-vessel, with space between the cover and the neck or mouthto permit the discharging material to escape therefrom, whereby the heat in the receiving-vessel is largely retained, 'a revoluble actuating-shaft rotating the receiving-- vessel as it revolves, and means for rotating the actuating shaft, substantially as described.
